Title: Layer capacitor production quality control - has electrode test strip material applied to substrate and coated for capacitance etc. tests
Inventor: BEHN REINHARD DIPL PHYS
IPC: H01G13/00
Filed: 1980-07-30
Abstract: The quality control monitor is for layer capacitor production by using test strips. A test strip is applied to a series of capacitor substrates and is coated in the same way. The metal strips have dielectric between them so that they can be measured. The first strip is applied to the substrate and its conductivity is verified, then the dielectric material and a second strip are applied, during normal capacitor production,and the capacitance can then be verified. The capacitors are made by feeding the substrate material over drums with cut-outs over a vacuum frame. The cut-outs are the former for electrode and test strip application. The test strip is fed from a roll in the production machinery.

Title: DC voltage source for variable load supply - uses compensation of non-linearity between load voltage and current in dependence on specified function
Inventor: HOHENLEITNER FRIEDRICH ING GRA
IPC: G05F1/575
Filed: 1980-09-30
Abstract: The voltage source is for a load with highly variable power requirements. Its output is controlled to a constant voltage value by a servo-element of a control voltage in connection with a circuit regulating an interference magnitude. A non-linearity, caused by circuit portions (NN) between the control output and the load input (V), is compensated by adjustment of a control magnitude between the load voltage (Ua) and the load current (Ia), forming the interference magnitude. Pref., a control value, formed according to the non-linear function, is superimposed onto the control deviation at the input of an amplifier (HIR) of the control circuit. The function values may be simulated in dependence on a circuit with the load current proportional voltage (Ui) and with parallel d.c. voltage amplifiers with different preset operating points, parallel connected at inputs and outputs.

Title: Process and installation for extracting cobalt
Inventor: FABER PETER DIPL CHEM DR
IPC: C01G51/04
Filed: 1981-04-04
Abstract: The invention is based on a process for extracting cobalt from cobalt substances, especially from cobalt-containing residues and/or ores. The cobalt substances, after size reduction by crushing if required, are digested to give an acidic solution. The cobalt is precipitated from the acidic solution in the form of cobalt compounds. In order to ensure that the cobalt compounds are precipitated free of interfering by-products and accompanying elements, the acidic solution is treated with ozone. Cobalt is then precipitated as an oxide with a valency of (III) and/or higher. Precipitation is predominantly carried out in the presence of buffer salts in the pH range of from 3 to 7. The invention also relates to an installation for carrying out such a process. This installation is equipped with a precipitation reaction vessel which is connected to an ozone generator. The acidic solution, together with the buffer salts where required, is circulated via a treatment vessel, where digestion to give the acidic solution is carried out.

Title: Apparatus for recycling material in strip form
Inventor: BRAUN SIEGFRIED
IPC: B29C48/03
Filed: 1981-10-01
Abstract: For the simple recycling of material in strip form, in particular from the edge trimming of flat-film and blown-film lines as well as film tape lines, it is proposed to compact the unstretched edge strips by means of a stuffing box tube (11), upstream of which there are a pair of feed rolls (14, 15) and possibly a folding die (16), and to feed the plug (12) produced to a barrel section (3) of the extruder barrel (1) which lies upstream of the hopper housing (6) in the direction of extrusion. This has the advantage that the screw channel of the extruder screw (7) is not yet filled here. When the extruder screw (7) turns past the bore (10) of the barrel section (3), the sharp-edged screw flight (8) cuts the plug (12) up regularly into pieces, which are melted in the melting zone of the extruder with the polymer filled in the hopper housing (6) and are mixed into the melt. <IMAGE>

The device has few joints and a small number of mechanical parts and is therefore particularly uncomplicated and inexpensive to manufacture. <IMAGE>
Patent DE-3148033-A1 (DE)
Title: Withdrawal machine for a horizontal continuous casting installation
Inventor: GUERTNER KLAUS-PETER
IPC: B22D11/128
Filed: 1981-12-04
Abstract: The invention is based on an intermittent mode of operation, known per se, in a withdrawal machine for strands with a still molten core emerging from a horizontal continuous casting installation. At the transition from the holding time to the withdrawal time, the emerging strand is pushed back for a comparatively short time. For this mode of operation, very small time intervals have to be specified since 100 to 250 cycles per minute are to be maintained in the casting of steel. Due to their inherent inertia, the drives of the contact pressure means which transmit the withdrawal force to the strand are structurally very complex. In order to arrive at more easily constructed drives with less expenditure, the invention provides that the contact pressure means be driven uninterruptedly in the withdrawal direction and in each case be capable of being pressed against the strand shell only for the duration of the withdrawal time. The invention furthermore provides additional contact pressure means which can be driven in the opposite direction to the withdrawal direction and are in each case pressed on only for the brief period of the push-back time. This eliminates the necessity for the additional braking and reacceleration of the contact pressure means with their drives within the period of action, which is in any case only short. In this way, it is possible to configure the withdrawal machine in such a way that it can follow clock generator control substantially without inertia, allowing the maintenance of an optimum mode of operation.

Patent DE-3204300-A1 (DE)
Title: Method for closing a container for the final storage of radioactive substances having a cover, and a storage device for carrying out the method, the container and/or cover consisting of a ceramic or metallic material
Inventor: BIENEK HEINZ ING GRAD
IPC: B65D53/00
Filed: 1982-02-09
Abstract: In the final storage of radioactive substances in containers, the latter must be sealed in a gastight fashion by a cover before the container is inserted into a final storage site. In order to avoid the previously customary thermal loading of the radioactive substances, on the one hand, and of the container and cover, on the other hand, it is proposed that the container (1) and the sealing cover (2) are matchingly ground in in their mutually assigned bearing regions (1a) and (2a), and that when the container (1) is closed the cover (2) is held biased on the bearing region of the container. Preferably, after the grinding a thin compensating layer made from a highly corrosion-resistant, deformable material is applied to at least one of the bearing surfaces of the container and cover, in order to achieve a compensation of the roughnesses still present that improves the seal to the extent of grinding that can be achieved in accordance with what is technically possible and/or economically achievable. It is, however, also possible to build up the biasing via a lapping engagement. <IMAGE>
